Think im in the right spot now
Okay have a few flights coming up in July for into Euro and back to the states in on SA metal
July 5 TAP full econ AMS-LIS
July 10 London Heathrow-Istanbul full econ (showed 50% bonus)
July 12 IST-DFW with stops in Geneva and Montreal in biz with AC
since Ive mainly fly AA/DL metal, wanting to know which account I should start to build my miles with Star Alliance.

Any strategy or mapping would greatly help
